Audio stuttering on many Proton games ChimeraOS that had no issue before.
I have been using ChimeraOS on my living room PC and it has worked well most of the time without issues. Recently I had audio stuttering on a new game and fixed it by using an older Proton build. But then I started a game that I have played many hours on this machine without any issue and suddenly had audio stuttering again on this title that previously had no audio issue with. Then I realized it is a problem with most of my library... This is really annoying for some title.
Anyone experienced something similar recently ? I have updated ChimeraOS twice since and updated the Proton Experimental build etc... Don't know if it is related to Proton, to a driver, to Chimera... How could I debug this ?
I've had a similar problem across various distros and several years: everything is fine for a while, then suddenly several games have audio crackling issues. I can usually (but not always) solve this with a PULSE_LATENCY_MSEC=60 %command% in the launch options; sometimes a different number, such as 20 or 30, works better.
